FRANK O. MCQUEEN, OF SOOTTSBURG, INDIANA.

ACETYLENE-GAS GENERATOR.

SPECIFIOATION forming' part of Letters Patent N o. 639,929, clated December 26, 1899.

Application filed April17,1899.

T0 all whom it mety con/carm- Be it known that I, FRANK O. MCQUEEN, a citizen of the United States, residing at Scottsburg, in the county of Scott, State of Indiana, have invented certain new and useful Improvements in Gas-Generators, of which the following is a specification, reference being had therein to the accoxnpanying drawing.

This invention relates to gas=generators,and particularly to a generating-chamber for use in connection with that class of apparatus.

The invention has for its object to simplify and improve the construction of the generating-chamber, so that a series of the same can be connected to a main and the gas generated therefrom discharged into a suitable gasometer.

A further object of the invention is to provide a carbid-receptacle which is readily removable from the generating-chamber and when used 'in connection with said chamber provides an outlet for the gas, which prevents any back pressure from the main when the chamber is open and also washes the gas as the same passes into the main.

Other objects and advantages of the invention will hereinafter appear in the following description and the novel features thereof will be particularly pointed out in the appended claim.

In the drawing I have illustrated a Vertical cross-section through the generating-chamber and the gasometer operatively connected therewith.

Like letters of reference indicate like parts throughout.

The letterA represents a removable carbidreceptaole, which is provided with an upwardly-extending tube or pipe A', terminating about midway its height. The receptacle is provided with suitable handles A to facilitate its removal and upon its lower surface with supporting-feet A3, which permit a circulation of the water beneath the bottom of the receptaole to cool the same. The receptacle is located within a generating-chamber B, which chamber is provided at its lower portion with a water or liquid seal chamber B', the upper wall B2 of which. supports the carbid-receptacle. This wall B2 also supports a vertically-extending gas-pipe B3, which extends upwardly adjacent to the top of the re- Serial No. '713 ,432. (No model.)

ceptacle and downwardly adj acent to the botltom of the chamber B' and below the level of the water contained therein. w An Outlet-pipe B4 extends through the bottom of the chamber B' and is provided with an outlet-aperture B5 to'permit the outflow of water from the chamber when the level therein rises beyond a predetermined limit.

A bell 'or dome O surrounds the upper portion of the carbid-receptacle A, and the lower end thereof extends downward Within the body of water located in the lower portion of the casing B to prevent the escape of gas. This bell or dome is `provided with a handle O' to facilitate its removal whenlit is desired to remove the carbid-receptacle. A suitable cover D is also fitted above said handle,and a pivoted locking-bar D' and spring-latch D2 may be provided to hold the cover or dome in its position against the pressure of gas beneath the same. A suitable water-feed c'onnection B6 is provided at one side ofthe casing B for the introduction of water into -the same.

The parts heretofore described maybe used in connection with any form of water-feed device-for instance, that shown in the drawing, wherein a gasometer E is provided with a movable dome E', carrying a suitable weight E2 and provided at its lower portion with a drying-chamber E3, adapted to contain any suitable substance for removing the moisture from the gas. A gas-inlet pipe F extends upward from this chamber, and a similar outletpipe F' extends downward from the upper part of the dome E2. A guide-rod F2 is supported from the chamber E3 and operates in connection with a tubular guide F3, carried by thedome E'. The gas is conveyed from the generating-chamber by a main or pipe G,

which is connected with the Outlet-pipe B4,`

and any desired number of generators may be located upon this main, which at one' end discharges the gas into the drying-chambei` E3. The main is also provided with a suitable water-trap G', which permits the escape of water collected therein.

For the purpose of effecting the water-feed a water-chamber H is supported from a suit-v able support E4 by means of a fiexible cable or other connection H', extending from thev top of the dome and over suitable guide-pul- IOO leys E5. The lower portion of this waterchamber is provided with a fiexible connection H2, which communicates with a suitable opening in the side of the generating-chamher, so as to establish therein a water-level equal to that within the water-Chamber. It will be seen that in the downward movement of the dome this chamberH will be elevated and the Water-level Within the generating-chamber thereby increased and the generation of gas started. The rising movelnent of the dome E' Will eifect the opposite operation and also the Water-level Within the generating-chamber, so that the generating operation is suspended.

From the foregoing description it Will be seen that the Water will pass over the upper end of the tube A', following the sides thereof and moistening the carbid at the base of the chamber. The movement of the Water beneath the carbid receptacle maintains the lower` surface of the same in a cool condition, and the gas as generated passes beneath the dome O, thence downward through the gaspipe BS and Water seal B' into the main G, from whence it is discharged into the gasometer, and from that point into the service system a's desired. The increase or decrease of gas within this dome E' Will effect the Water-feeding operation, as hereinbefore desoribed, and When the carbid-receptaele is removed from the generating-chamber for the ,purpose of recharging 4o'r cleansing the Water seal in the chamber B' will prevent any escape of gas.

It is obvious that numerous changes may be made in the details of construction and configuration of the several parts without departing from the spirit of the invention as defined by the appended claim.

Having described my invention and set forth its merits, What I claim, and desire to secure by Letters Patent, is-

In a gas-generator, the combination of a casing having a water seal in its lower portion, a carbid-receptacle resting upon said seal and provided With an u pward tubular ex-
